Insulating Your Attic in the Winter

When it comes to attic insulation, many people think of warm climates and installing materials to help keep your home cool and comfortable. But attic insulation helps keep homes warmer and cooler—so insulating in the winter is important too!

Although it’s mild here in the Sacramento area most of the year, it can get pretty cold, especially in December and January. Now is the time to start thinking about installing insulation so you can keep your energy bills in check during the colder months.

How Attic Insulation Works in the Winter

In the summer, and in regions that stay warm for the majority of the year, attic insulation works like this: radiant barrier or foil insulation is installed in the ceiling to help the roof reflect, rather than absorb, heat from the sun. This is especially useful for homes with asphalt roofing (which absorbs sunlight easily) and little to no shading from trees.

But how does attic insulation work when it’s cold? Well, attics are some of the biggest sources of energy loss in homes. Heat rises, and it can leak out of your home if your attic isn’t well insulated. Attic insulation traps heat that would otherwise escape. Thermal, rather than foil, insulation materials are used for this purpose—such as fiberglass or cellulose.

Tips for Insulating the Attic

For the best results, keep these expert tips in mind:

  • Remove old insulation: Attic insulation can get damaged—from old age, mold, rodents, etc. If you have old or damaged insulation in your attic, our professionals will remove it before installing new insulation.
  • Air seal: Attic insulation and sealing go hand-in-hand because air leaks can undermine the performance of insulation. An attic (or home) that is insulated but not air sealed isn’t as energy-efficient as it could be!
  • Get an energy assessment: A home energy audit can help you detect places other than the attic that need more insulation. It’s the first step towards getting your home on the right path to maximum energy efficiency.
